UNITED STATES PATENT OFFICE.

JOSEPH W. BRIGGS, OF CLEVELAND, OHIO.

IMPROVED STlTCHlNG-MACHINE.

Specification forming part of Letters Patent No. 34,938, dated April 15,1862.

To all whom it may concern.-

Beit known that I, JOSEPH W. BRIGGs, of the city of Cleveland, in thecounty of Ouyahoga and State of Ohio, have invented a new and usefulImprovement on the Stitching- Machine; and I do hereby declare that thefollowing is a full and exact description there-A of, reference beinghad to the accompanying drawings, in Which- Figure l is a View inperspective of a stitching-machine; and Fig. 2, a portion ofthe sameenlarged, showing the application of my invention.

My improvement consists in the imployment of an eye-pointed needle,which is inserted in the piston-rod of a stitching-machine, said machinebeing similar 4in all other respects to that for which a patentwasgranted to Joseph W. Briggs, Luther O. Garner, and John S. Garner on the26th day ot' March, A. D. 1838, the said eye-pointed needle being usedin connection with the vibrating arm of said machine, operated by thetread motion thereof, for the purpose of stitching leather, textilefabrics, 8vo., the stitch being secured or fastened, aswill beexplained.

The construction of the body of the machine on which my said improvementis used is substantially the same as that described in the speciiicationof the said Briggs and Oarners 5 but in place of the pricking-awl Iinsert-a needle constructed With an eye near its point. A, Fig. 2, isthe saidneedle, and B its eye. G is a part of the vibrating arm,showingits connection with the needle by means ofthe strap D.

The operation is as follows: l inserta thread through the eye of saidneedle, which is then forced through the article tobe stitched, heldbetween the jaws of the sliding clamps of the machine by the motion ofthe treadle. I then pass a common hand-needle and its thread by handthrough each of the loops of the other thread, on the back of thefabric, as they are successively formed by the action ofthe vibrating`arm and feed motion of the machine. When the common needle and itsthread are passed through the loops, with the point of the said needletoward the body of the operator as he or she may sit upon the seat ofthe machine, the thread carried by the eye-pointed needle and the threadof the common needle cross each other in forming a stitch, and the loopsof the threads are drawn within the body of the substance stitched,presenting the appearance of a fair stitch on each side of the seam.This seam, thus formed, if in leather or equivalent material, may easilybe opened; but when the common needle, with its thread, is passedthrough the loops, with its point passing from the body of theoperator,the thread of the common needle is coiled around the threadcarried by the eye-pointed needle, and forms, with stitches thus made, amore durable seam, and one that cannot be so easily opened as the seamabove described.

I do not claim the method of pricking the4 holes by means of a slidingawl, or the method of working and regulating the motion of the slidingclamps, as these devices are embraced in the said Briggs and Oarnerspatent, dated March 26, 1838, for a stitching-machine for stitchingharness, Src.; but

What I claim as my improvement, and desire to secure by Letters Patentof the United States, is

The combination of the eye-pointed needle A, the vibrating arm (l, strapD, and treadle With a feed mechanism, When the several parts areconstructed and arranged as described, and for the purposes set forth.

JOSEPH W. BRIGGS. In presence of- EARL BILL, WM. A. DOLE.
